Tottenville Republican Alex Zablocki interviewed with the Brooklyn GOP last night in a bid to get their endorsement for his run for public advocate.

"It went well," Zablocki said of the meeting with Brooklyn Republican chair Craig Eaton and about half a dozen party executive committee members.

The Brooklynites were conducting interviews for a number of seats.

Zablocki, an aide to GOP state Sen. Andy Lanza, said the Kings County group asked him if he would primary if he didn't get the party's endorsement. Zablocki said he would.

"Maybe it was a test," he told us. "Maybe they wanted to see if I was tough enough to stick it out, or if I would cave."

The Brooklynites also asked him if he liked City Councilman Jimmy Oddo (Zablocki said yes) and Mayor Mike Bloomberg.

Zablocki said he backs the mayor -- whom the Brooklyn GOP voted to support last week -- despite his misgivings over Bloomberg's property-tax hike.

"At the end of the day, he's been there for Staten Island," said Zablocki. "He's the best choice."

Bronx Republican Juan Carlos Polanco has also looked at the race, and Eaton said that another as-yet-unnamed Republican had expressed interest as well.

"He was well-spoken and articulate," Eaton said of Zablocki. "He seems like a good candidate. We have to go through our process."

In any event, Zablocki acknowledged to us that he faces an uphill climb. He needs to raise $125,000 in order to qualify for the city's matching-fund program.

"I'm not even close to that," he said.

But running on a shoestring budget has its advantages, Zablocki told us. While the other candidates are bashing each other through million-dollar direct-mail and TV advertising, Zablocki said he could run a door-to-door "ground campaign" for around $10,000.

For example, he said he could print 100,000 postcard-sized color palmcards for about $1,600 and have volunteers distribute them all over the city.

"I kind of like going neighborhood to neighborhood," he said. "It is possible."
